Impact of magnetohydrodynamic and buoyancy‐driven forces on carbon nanotube‐water nanofluid

Present analysis brings out the study of an electrically conducting carbon nanotube (CNT) water-based nanofluid flow occurrences with the existence of buoyant forces. Inclusion of the impact of thermal radiation in the energy balance also enhances the heat transfer characteristics of nanofluid. Due to considerable interest in the conductivity of CNT's and practical applications in industries, its study plays an important role. Closed form solution does not hold good for the nonlinear coupled system into nonlinear ODE. For the solutions, we have employed a semianalytical technique baptized Adomian Decomposition Method (ADM) with suitable guess solutions using initial conditions. The influence of physical restrictions describing the flow behavior is presented through figures. The outcomes of numerical validation for the rate of heat, shear stress, and mass transfer coefficients are also presented in tabular form. The physical phenomena of these parameters are also discussed in the discussion section for stretching surfaces. It is observed that the CNT nanoparticle volume fraction is favorable to enhance the fluid temperature, and more importantly, in comparison to pure fluid, CNT-water nanofluid retards the velocity greatly which is an important phenomenon for the production of materials in industries.
